#OgdenSummer

Guidry has been working in Dr. Drew Steen's lab in the Department of Earth and Planetary Sciences as a part of the University of Tennessee, Knoxville's Microbial Community Interactions and Functions REU (Research Experience for Undergraduates).

Dr. Steen's group studies marine subsurface microbes and their novel metabolisms. Guidry’s project for the summer has been optimizing a protocol to extract subsurface sediment microbial proteins (from the White Oak River estuary in North Carolina) for proteomic analysis. Their goal is to isolate these proteins to see how heterotrophic subsurface microbes with metabolisms on the scale of thousands of years are using carbon sources that are 100 million+ years old.
